The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

With the continuous development of washing machine technology, the washing machine tends to be intelligent. When a user uses the washing machine, the user can start the washing machine by one key after putting clothes in the washing machine, and the washing machine can directly take out the washed clothes. Washing machines have become an indispensable part of homes, and not only can clean clothes, but also can save time for users to clean the clothes.

The embodiment of the present application provides a washing machine 100, as shown in fig. 1, which is a schematic diagram of the washing machine of the embodiment of the present application, the washing machine 100 may further include a housing 1, a cover plate 2, an outer tub 3 and an inner tub 4, wherein the housing 1 has a mounting cavity 11, the outer tub 3 is mounted in the mounting cavity 11 and connected to the housing 1, and the mounting cavity 11 has an opening communicated with the mounting cavity 11. The cover plate 2 is movably connected with the shell 1, and the cover plate 2 is used for covering the opening of the shell 1. The outer barrel 3 has a containing cavity 31, the inner barrel 4 is installed in the containing cavity 31, and a gap is formed between the side wall of the inner barrel 4 and the side wall of the outer barrel 3. The inner tub 4 has a washing chamber 41 for washing laundry.

In this case, as shown in fig. 1, when washing laundry, the cover 2 is opened, and the laundry is placed in the washing chamber 41 of the inner tub 4 and then the cover 2 is closed. The washing machine 100 is started, the washing water enters the washing chamber 41 of the inner tub 4, the washing chamber 41 and the gap between the inner tub 4 and the outer tub 3 are filled with the washing water, the water stops entering after the washing water in the inner tub 4 reaches a certain level, and the washing machine 100 starts washing. Specifically, the washing water and the laundry in the inner tub 4 begin to tumble, and the laundry rubs against each other, and the tumbling laundry and the sidewall of the inner tub 4 repeatedly rub against each other to achieve the washing purpose. After washing, the washing water is drained, and then the clothes are dehydrated. Specifically, when the washing machine is operated to spin, the inner tub 4 is rotated at a high speed, and a part of the washing water in the inner tub 4 is discharged to a gap between the inner tub 4 and the outer tub 3 by centrifugal force, and then discharged to the outside of the washing machine 100.

Since the washing water is contained in the washing chamber 41 of the inner tub 4, the washing water in the washing chamber 41 may cause the inner tub 4 to be shaken when tumbling, in order to reduce the eccentric force generated from the inner tub 4. In some embodiments of the present application, the washing machine 100 may further include a balance ring 5 as shown in fig. 2, and specifically, the balance ring 5 may include a balance ring body 51, and the balance ring body 51 is located at an end of the inner tub 4 away from the bottom wall of the inner tub 4 and is disposed around the inner tub 4. In this case, when the washing water does not tumble in the washing chamber 41 of the inner tub 4, as shown in fig. 3, the sidewall of the inner tub 4 is in a parallel state with the sidewall of the outer tub 3. When the washing water in the washing chamber 41 of the inner tub 4 rolls over, as shown in fig. 4, the balance ring body 51 on the top of the inner tub 4 and the inner tub 4 still generates a certain deviation during rotation, and when the deviation occurs, the balance ring body 51 first touches the inner wall of the outer tub 3. In order to prevent the abrasion between the inner tub 4 and the outer tub 3, the gap between the inner tub 4 and the outer tub 3 must be increased, however, this causes problems of an increase in washing water and an increase in the cost of the whole machine. Therefore, in some embodiments of the present application, as shown in fig. 6, a cross-sectional view at a-a of the gimbal 5 of fig. 5, and for a clearer illustration of the structure of the gimbal 5 of the present application, as shown in fig. 7, an enlarged schematic view at B of fig. 6. A first avoidance notch 511 is formed at a position outside the upper portion of the balance ring body 51 (i.e., a side of the balance ring body 51 away from the inner barrel 4 and close to the outer barrel 3), and the first avoidance notch 511 is disposed around the balance ring body 51.

In this case, when washing the laundry, as shown in fig. 4, the laundry may be placed in the washing chamber 41 of the inner tub 4, and then the washing machine 100 is started, and the washing water enters the washing chamber 41 and flows between the inner tub 4 and the outer tub 3. When the laundry is washed in the washing chamber 41, the balance ring body 51 at the upper end of the inner tub 4 can offset a part of the eccentric force generated when the inner tub 4 rotates, so that the inner tub 4 can rotate in the receiving chamber 31 of the outer tub 3. However, when the balance ring body 51 rotates with the inner tub 4, the outer surface of the balance ring body 51 contacts the inner wall of the outer tub 3. Thus, the contact portion between the balance ring body 51 and the inner wall of the outer tub 3 is worn, which affects the mechanical strength of the balance ring body 51 and the outer tub 3, thereby affecting the service life of the washing machine 100. As can be seen from fig. 4 and 7, the balance ring body 51 is far away from one end of the inner tub 4, and a first avoiding notch 511 is formed at a side close to the outer tub 3, and the first avoiding notch 511 is disposed around a circumference of the balance ring body 51. Thus, the first avoiding notch 511 is located at the contact position between the balance ring body 51 and the outer tub 3, so that the distance between the balance ring body 51 and the inner wall of the outer tub 3 at the contact position is increased, and the risk of the inner tub 4 colliding with the outer tub 3 after being inclined is reduced.

In addition, under the condition that the diameter of the inner barrel 4 is not changed, the diameter of the outer barrel 3 matched with the balance ring body 51 provided with the first avoidance notch 511 can be reduced compared with the balance ring body 51 not provided with the first avoidance notch 511. Thus, the clearance between the outer wall of the inner barrel 4 and the inner wall of the outer barrel 3 is reduced, and the water storage quantity between the outer barrel 3 and the inner barrel 4 is reduced, thereby achieving the purposes of saving water and reducing cost.

For example, in some embodiments of the present application, as shown in fig. 8, a longitudinal section of the first avoiding notch 511 may be a straight line, and the longitudinal section is perpendicular to the bottom wall of the inner barrel 4, and the longitudinal section forms an angle with the side of the balance ring body 51 near the outer barrel 3, so that the first avoiding notch 511 forms an oblique angle. In this case, the interval between the surface on which the bevel is shrunk and the inner wall of the outer tub 3 is greater than the interval between the balance ring body 51 and the inner wall of the outer tub 3. When the inner tub 4 of the washing machine 100 is rotated, the balance ring body 51 may avoid the outer tub 3. The probability that the bevel of the balance ring body 51 is contracted to abut against the inner wall of the tub 3 is greatly reduced, and therefore, the abrasion between the balance ring body 51 and the inner wall of the tub 3 can be reduced.

In other embodiments of the present application, as shown in fig. 7, the first avoiding notch 511 may have an L-shaped longitudinal section, and the longitudinal section is perpendicular to the bottom wall of the inner barrel 4. In this case, the first relief notch 511 may include a first face 5111 and a second face 5112. Wherein, the first face 5111 is parallel to the inner wall of the tub 3. And a second face 5112 connected to the first face 5111, wherein the second face 5112 is close to the bottom wall of the inner barrel 4 relative to the first face 5111, the first face 5111 is connected to the second face 5112, and the connection between the first face 5111 and the second face 5112 is a cambered surface. As such, the first face 5111, the second face 5112 and the arcuate faces form a large fillet constriction. Big fillet shrinkage structure intensity can be stronger than oblique angle shrinkage intensity, is difficult to produce the deformation, and the dislocation condition of leaking can be avoided in the cladding process, and at the cladding in-process, the cladding outer wall atress is good on the frock, and it is firm to clad.

In order to prevent the washing water between the inner tub 4 and the outer tub 3 from flowing out of the outer tub 3, in other embodiments of the present application, the washing machine 100 may further include an annular outer tub cover 6 as shown in fig. 9, wherein the annular outer tub cover 6 is installed between the balance ring body 51 and the outer tub 3 and is disposed on a side of the balance ring body 51 away from the bottom wall of the inner tub 4. Fig. 10 shows the mounted schematic view, and fig. 11 shows a cross-sectional view of fig. 10 along the direction C-C for more clearly explaining the technical solution of the present application, so that the sealing performance between the inner tub 4 and the outer tub 3 is improved after the annular outer tub cover 6 is mounted.

In order to reduce the distance between the annular outer barrel cover 6 and the balance ring 5, clothes are prevented from entering between the inner barrel 4 and the outer barrel 3. The balance ring 5 may further include a balance ring protrusion 52 as shown in fig. 12, the balance ring protrusion 52 is annular and is disposed on a side of the balance ring body 51 away from the bottom wall of the inner tub 4 and located at an end of the balance ring body 51 away from the outer tub 3, and the balance ring protrusion 52 is connected to the balance ring body 51. Wherein, the part of the annular outer barrel cover 6 close to the balancing ring projection 52 has an overlapping area with the balancing ring projection 52. The balance ring projection 52 is close to the side wall of the outer barrel 3, and a second avoiding gap 53 is formed between the balance ring body 51 and the surface of the bottom wall far away from the inner barrel 4. In the case that the longitudinal section of the first avoiding notch 511 may be L-shaped, the surface of the balance ring body 51 away from the bottom wall of the inner barrel 4 is connected to the first face 5111.

Thus, since the part of the annular outer barrel cover 6 close to the balance ring projection 52 has an overlapping area with the balance ring projection 52, the height of the balance ring projection 52 is higher than the height of the annular outer barrel cover 6 close to the balance ring body 51, and there is no gap between the balance ring projection 52 and the balance ring body 51 in the height direction. When the inner tub 4 of the washing machine 100 rotates, the laundry in the washing chamber 41 of the inner tub 4 does not slip between the inner tub 4 and the outer tub 3 due to centrifugal force to wear the laundry. Meanwhile, the balance ring projection 52 can be internally provided with a liquid storage cavity communicated with the balance ring body 51, so that the internal volume of the original balance ring 5 can be enlarged, and the balance effect of the balance ring 5 is enhanced.

In this case, since a part of the annular outer barrel cover 6 is inserted between the balance ring 5 and the inner wall of the outer barrel 3, when the inner barrel 4 rotates, the balance ring 5 on the upper portion of the inner barrel 4 also touches the part of the annular outer barrel cover 6 between the balance ring 5 and the inner wall of the outer barrel 3, and the first avoiding gap 511 can also improve the abrasion between the balance ring 5 and the annular outer barrel cover 6.

The above mentioned structure of the balancing ring 5 is exemplified below, for example, in some embodiments of the present application, the liquid storage chamber of the balancing ring 5 may be filled with saturated saline, the saturated saline can flow, and when the clothes are not uniform during dehydration, the water of the balancing ring 5 can provide a supplementary weight to maintain balance. In other embodiments of the present application, a calcium chloride solution may be added to the liquid storage chamber of the gimbal 5, and the liquid added to the gimbal 5 is not limited in the present application.

In order to make the connection between the inner barrel 4 and the balance ring 5 more stable, in other embodiments of the present application, as shown in fig. 12, which is an enlarged schematic view of a position D in fig. 11, the balance ring body 51 is close to one end of the inner barrel 4, a third avoiding notch 7 is formed at a side of the balance ring body 51 close to the outer barrel 3, the third avoiding notch 7 is disposed around a circumference of the balance ring body 51, and the third avoiding notch 7 abuts against an inner wall of the inner barrel 4.

In this case, since the third avoiding notch 7 is located at the lower part of the balance ring body 51, the third avoiding notch 7 can be matched with the inner wall of the inner barrel 4, so as to prevent the diameter of the inner wall of the inner barrel 4 from being larger than that of the outer wall of the balance ring body 51. The third avoiding gap 7 can be abutted against the inner wall of the inner barrel 4 to form a joint, so that the connection between the inner barrel 4 and the balance ring 5 is more stable.

In order to clean the clothes in the inner tub 4 of the washing machine 100, in some embodiments of the present application, the washing machine 100 may further include a plurality of agitation bars 8, as shown in fig. 11, disposed on an inner wall of the inner tub 4 and connected to the inner tub 4. The above-mentioned structure of the agitating rib 8 is exemplified below, for example, the agitating rib 8 may have a polygonal three-dimensional structure, and a portion of the agitating rib 8 is located in the washing chamber 41 of the inner tub 4. In this way, the agitation bars 8 may agitate the washing water and the laundry in the inner tub 4, thereby making the laundry cleaner. In other embodiments of the present application, the stirring rib 8 may also be a protrusion with a circular arc surface, in which case, the circular arc protrusion has less wear on the clothes, and the circular arc protrusion may also play a role in stirring the clothes.

After the washing machine 100 is cleaned, a drain hole is opened on the bottom wall of the inner tub 4 in order to drain the washing water in the inner tub 4. To power the tumbling of the washing water in the inner tub 4, in some embodiments of the present application, the washing machine 100 may further include a pulsator 101 and a motor 102 as shown in fig. 13. Wherein, the impeller 101 is located in the washing chamber 41 and covers the drainage hole. The motor 102 has a rotating shaft disposed outside the outer tub 3, the rotating shaft is connected to the pulsator 101, and the motor 102 is used for driving the pulsator 101 to rotate relative to the outer tub 3. The shaft is also connected to the bottom wall of the inner tub 4, and the motor 102 is also used for driving the inner tub 4 to rotate relative to the outer tub 3.

In this case, as shown in fig. 13, when the washing machine 100 is started, the motor 102 rotates, and when the laundry is washed, the motor 102 rotates the pulsator 101, and the pulsator 101 rotates forward for a certain time, and then rotates forward again, so that the laundry is repeatedly agitated to achieve a washing effect. When the clothes are washed, the washing water in the inner tub 4 can be discharged through the water discharge hole at the bottom of the inner tub 4. When clothes need to be dried, the motor 102 can be controlled to drive the inner barrel 4 to rotate, the stirring ribs 8 on the inner wall of the inner barrel 4 collide with the clothes and the clothes are dried along with the eccentric force, and a part of drying washing water can flow into the space between the inner barrel 4 and the outer barrel 3 and then is discharged from the bottom of the outer barrel 3.

In order to switch the motor 102 between driving the pulsator 101 and rotating the inner tub 4, in some embodiments of the present application, the washing machine 100 may further include a clutch 103 shown in fig. 13, the clutch 103 is connected to a rotating shaft of the motor 102, and the clutch 103 is also connected to both the pulsator 101 and the inner tub 4. The motor 102 drives the pulsator 101 to rotate relative to the outer tub 3 through the clutch 103, and the motor 102 is also used to drive the inner tub 4 to rotate relative to the outer tub 3 through the clutch 103.

Thus, when the washing machine 100 is started, the motor 102 rotates to drive the clutch 103 to rotate, the clutch 103 may be connected to the pulsator 101 when washing laundry, and the clutch 103 may be connected to the inner tub 4 when dehydrating. In this case, the connection between the motor 102 and the pulsator 101 and the inner tub 4 may be switched by the clutch 103, thereby achieving the effects of washing the laundry and dehydrating.

In order to enhance the washing effect of the washing machine 100, in some embodiments of the present application, the washing machine 100 may further include a plurality of water-repellent ribs 1011 shown in fig. 14 disposed at a side of the pulsator 101 adjacent to the inner tub 4 shown in fig. 13 and connected to the pulsator 101. The pulsator 101 is provided with a plurality of water return holes 1012.

In this case, since the water repellent ribs 1011 protrude from the upper surface of the pulsator 101, when the laundry is prevented from being on the upper surface of the pulsator 101, the rotation of the pulsator 101 may rotate the laundry. And the water poking rib 1011 can stir the washing water in the inner barrel 4, so that the washing water in the inner barrel 4 rolls more strongly, and the clothes soaked in the inner barrel 4 are cleaned more cleanly. After washing, the washing water in the inner tub 4 can flow into the water discharge hole on the bottom wall of the inner tub 4 through the water return hole 1012 on the pulsator 101 and then be discharged.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
